The ratio of males, females and children are in the ratio 3 ∶ 4 ∶ 5. If males increased in the ratio 4 ∶ 5 and females increased in the ratio 5 ∶ 6 and children increase in the ratio 3 ∶ 4. What is the ratio of males, females and children after increased? Correct Answer 225 ∶ 288 ∶ 400
Let the ratio of males, females, and children are 3x ∶ 4x ∶ 5x.
New ratio after increase = 3x × ∶ 4x × ∶ 5x ×
Take LCM of denominator (4, 5, 3) = 60
60 multiply this 3x × ∶ 4x × ∶ 5x ×
We get 3x × 5 × 15 : 4x × 6 × 12 : 5x × 4 × 20
225 ∶ 288 ∶ 400
